Abstract
The present invention relates to a method for dimensioning a turbomachine comprising a casing and a disc to which at least one blade is secured, said disc being rotationally driven by a shaft about a turbomachine axis (z), comprising: —acquisition (E) of the coordinates (P) of the ends of the leading edge and of the trailing edge of the blade in a frame of reference connected with the disc; —expression (E) of the coordinates (P') of the ends of the leading edge and of the trailing edge of the blade in a frame of reference connected with the casing; —calculation (E) of the distance (g) between the casing and the ends of the leading edge and trailing edge of the blade from the coordinates (P′) expressed in the frame of reference connected with the casing; —calculation (E) of the contact pressures between the blade and the casing along the end of the blade from the calculated distance (g); —calculation (E) of the reaction forces and moments resulting from contact between the blade and the casing from the calculated pressures; —dimensioning (E) of the turbomachine as a function of the calculated distances, pressures, forces and moments.
